There's rarely a dull moment in the Four-Cornered World: Harefolk Hunter's party is moving up the ranks and making a name for themselves on the frontier; Priestess, Female Knight, Witch, and High-Elf Archer get mixed up in a fortress siege battle; Goblin Slayer receives an invitation from Spearman and Heavy Warrior; and the people in the water town are up to their usual tricks.

Based on the episodic Vol 12 of the Light Novel skipped by the manga adaptation.
